Gregory Bentsen, Minerva University, Title of talk: Harnessing entanglement with cold atoms
Abstract: Quantum entanglement is one of the most salient, bizarre, and powerful features of quantum mechanics. Simple forms of entanglement can be used to teleport quantum information between distantly separated points; more complicated patterns of entanglement can be employed to facilitate universal quantum computation, or to simulate intractable problems in many-body physics. At present, the full range of complex entanglement accessible to a many-body quantum system constitutes a vast, largely unexplored frontier. One of the most exciting challenges for near-term experimental platforms is to engineer and exploit these complex patterns of entanglement for applications including precision metrology, many-body quantum simulation, and quantum information processing. In this talk I will introduce many-body quantum entanglement and discuss a few of its applications in an ensemble of neutral 87Rb atoms coupled to an optical resonator. The long-range, all-to-all interactions of this experimental platform provide unique capabilities for generating entanglement efficiently, by rapidly spreading quantum information throughout the system. I will demonstrate how the resulting patterns of entanglement can be harnessed to implement Heisenberg-limited precision metrology, to study quantum chaos, and to simulate aspects of gravitational physics such as black holes and holographic duality.
